Specifications and Features: .50 caliber. 245 grain. Polymer tip. Copper plated. Package of 50. CVA's copper plated PowerBelts have become the most popular muzzleloading projectiles since the roundball and truly are "the bullets that made sabots obsolete". They are #1 for a reason, and if you don't believe us, just ask any hunter who has shot them. The thin copper plating greatly reduces bore friction for higher velocities, while the polymer AeroTip insures consistent expansion.
